Accumulations of two to four inches are expected tonight through Thursday, and an additional one to three inches are possible Thursday night and Friday. Wind gusts could reach 40 mph inland and 50 mph along coastal areas this evening through Thursday morning. Winds this strong can make driving hazardous and cause road closures, so use extra caution on the roadways, especially in high-profile vehicles.
With temperatures in the low to mid 30s, a mix of rain and snow is expected to develop before changing to all snow late this afternoon. Moderate snow is possible tonight through Thursday morning, followed by periods of light to moderate snow Thursday afternoon through Friday morning.
Snow accumulations could lead to dangerous driving conditions tonight through Thursday. Periods of snow, sleet or freezing rain will cause slippery roads and limited visibilities; and heavy, wet snow in combination with strong winds could lead to downed tree branches and power lines. Thankfully, National Grid has been working to prepare the LIPA system for efficient and timely restoration work should outages occur.
A coastal flood advisory also is in effect for western and central Long Island Sound and the North Shore of Long Island from 5 p.m. this afternoon to 8 p.m. this evening, and a coastal flood watch remains in effect for Thursday morning.
A coastal flood advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore due to the height of the storm tide or wave splash over. Widespread minor to moderate coastal flooding could occur during high tide cycles this evening and Thursday morning.
Coastal residents should be alert for later statements or warnings and take precautions to protect property.
